A) 30mA
B) 40mA
C) 20mA
D) 35mA
Correct Answer: A
Solution :
Given, external resistance R = 100\[\Omega \] and an emf is 3.5V. Potential barrier across the diode is 0.5 V, Potential difference on \[R=3.5V-0.5V=3.0V\] Current in circuit, \[I=\frac{V}{R}=\frac{3}{100}=0.03A=30mA\]You need to login to perform this action.
